Hi,

I have 2 ISP.

ISP 1
2 Public IP
Working 100% with NAT etc. and main to navigate.

ISP 2
3 Public IP
When i connect it to the RB i dont receive ping response from outside, cant use nat, etc. SAME configuration in other RB is working 100%


I had this 2 ISP working together before, they stopped working when i changed ISP 1 modem to upgrade from copper to optic.

Help pls i have to separate LANs because of this

SAME configuration in other RB is working 100%

- single ISP2 connection can work normally

are you trying pings from(with source interface) or to 'RB or servers' with public IPs?
are you marking traffic from each ISP to flow back same direction?
